Resistive therapeutic wrist dynamometer and exerciser device

ABSTRACT

A resistive therapeutic device is disclosed such that upon a user applying torque a controller emits a signal to an electromagnetic resistance generating member. The controller detects a maximum torque applied by a user detects if the maximum torque applied by a user is less than or equal to a resistance setting. The torque resistance is variable from a neutral position to a maximum position, and the controller increases the resistance setting as a user moves a torque application member in a direction away from the neutral position that represents an increase in torque applied by the user. A control and user interface for a resistive therapeutic device includes an evaluation display of torque strength applied and displays an angle of rotation clockwise or counterclockwise directions ranging from 0 degrees to 360 degrees and a count of repetitive times a user has rotated at least 360 degrees in either direction.

CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims the benefit of, and priority to, U.S. Provisional Patent Application No. 62/299,617 by Dennis Waldman entitled “RESISTIVE WRIST DYNAMOMETER AND EXERCISER”, filed on Feb. 25, 2016, the entire contents of which is incorporated by reference herein.

BACKGROUND

Hand, wrist, and finger injuries may prevent people from performing actions that they may do in their natural environment, e.g., opening a door; turning a key; driving a car; opening a jar or water bottle; turning a screw driver, etc. These type problems may be also due to a stroke or aging.

In physical or occupational therapy, it is important to measure the patient's wrist strength and to use a resistive device to help exercise the motions described above.

The technology to be able to create a non-moving device that measures torque, change the resistance level and mode of operation, and to do all this smoothly and repeatedly is a challenge.

Providing a mechanical resistance similar to an exercise bike that has mechanical resistance applied against the flywheel does not provide a repeatable and measurable resistance.

SUMMARY

The present disclosure relates to a resistive therapeutic device that includes a torque application member enabling torque to be applied by a user. An electromagnetic resistance generating member in communication with the torque application member provides a resistance setting to the torque applied by a user. A controller in communication with the electromagnetic resistance generating member emits a signal to the electromagnetic resistance generating member upon a user applying torque to the torque application member. The controller detects a maximum torque applied by a user and detects if the maximum torque applied by a user is less than or equal to the resistance setting.

In embodiments, the torque application member is variable from a neutral position to a maximum position, and the controller increases the resistance setting as a user moves the torque application member in a direction away from the neutral position that represents an increase in torque applied by the user.

In embodiments, the resistance setting is adjustable to a specified turning angle during movement by the user of the torque application member and the specified turning angle represents a maximum resistance targeted for the user.

The present disclosure relates also to a control and user interface for a resistive therapeutic device that includes a master display and a link to an evaluation display wherein upon a user accessing the link to the evaluation display, the evaluation display displays a torque strength applied by a user to a torque application member.

In embodiments, the controller and user interface enables displaying an angle of rotation of the torque application member in a clockwise direction ranging from 0 degrees to 360 degrees or in a counterclockwise direction ranging from 0 degrees to 360 degrees, and enables displaying a count of repetitive times a user has rotated the torque application member to at least 360 degrees in either the clockwise or counterclockwise direction.

In embodiments, the control and user interface enables setting a reference angle to apply torque strength to a torque application member.

In embodiments, the controller and user interface enables setting a maximum value for the reference angle in the direction set as one of clockwise or counterclockwise, and upon setting the maximum value for the reference angle in the direction set as one of clockwise or counterclockwise, the controller and user interface enables setting an incremental torque increase versus angle increase as a user applies torque to the torque application member.

In embodiments, the control and user interface enables displaying at least one of a peak torque strength achieved by a user in the clockwise direction or an average of peak torque strengths achieved by a user in the clockwise direction or the controller and user interface enables displaying at least one of a peak torque strength achieved by a user in the clockwise direction or an average of peak torque strengths achieved by a user in the counterclockwise direction.

In embodiments, the controller and user interface enables displaying an angle of rotation of the torque application member in a clockwise direction ranging from 0 degrees to 360 degrees or in a counterclockwise direction ranging from 0 degrees to 360 degrees, and enables displaying a count of repetitive times a user has rotated the torque application member to at least 360 degrees or crossing 0 degrees in either the clockwise or counterclockwise direction.

The present disclosure relates also to a system for controlling input current to an electromagnetic resistance generating member that includes a controller and memory in communication with the controller. The controller and memory are configured to direct an input current to set torque resistance of an electromagnetic resistance generating member from one of an increasing current curve versus torque resistance or a decreasing current curve versus torque resistance or both an increasing current curve versus torque resistance and a decreasing current curve versus torque resistance wherein the curves are stored in the memory.

In embodiments, the controller recognizes direction of torque change as an increase or decrease in existing torque set point and the controller retrieves one of the increasing current curve versus torque resistance or the decreasing current curve versus torque resistance or both the increasing current curve versus torque resistance and the decreasing current curve versus torque resistance from the memory.

In embodiments, the controller decreases the torque resistance and current input to the electromagnetic resistance generating member when the current input is being adjusted along the increasing current curve and the controller pulses the input current to 100 percent of maximum input current.

In embodiments, the controller returns the pulsed input current to an input current value on the increasing current curve that represents an equivalent torque resistance to the torque resistance value on the decreasing current curve.

In embodiments, the controller directs continuing an increase in current along the decreasing current curve to a target torque resistance value.

In embodiments, the controller increases the torque resistance and current input to the electromagnetic resistance generating member when the current input is being adjusted along the decreasing current curve; wherein the controller applies a single direction pulse to 100 percent of maximum input current at the existing torque resistance value; wherein the controller circumvents adjustment of the input current on both the increasing current curve and on the decreasing current curve; and wherein the controller sets the input current value on the decreasing current curve that represents an equivalent torque resistance to the torque resistance value on the increasing current curve, thereby crossing the increasing current curve.

FIG. 1A is a general logic diagram for operation and control of embodiments of a resistive therapeutic wrist or shoulder dynamometer and exerciser device 1000 according to the present disclosure. The resistive therapeutic dynamometer and exerciser device 1000 includes an interchangeable torque application member 1100 that enables torque to be applied by a user of the device. The device 1000 includes an electromagnetic resistance generating member 1200 that is in communication with the torque application member 1100. The electromagnetic resistance generating member 1200 provides a target resistance setting and a resistance to the torque applied by a user of the device 1000 via the torque application member 1100.

The device 1000 further includes a controller 1300 that is in communication with the torque application member 1100 and the electromagnetic resistance generating member 1200. The controller 1300 contains therein or is in communication with a memory 1310.

The torque application member 1100 enables variation of the target resistance setting from a neutral resistance position 1110 to an intermediate resistance position 1120 to a maximum resistance position 1130. A turning angle 1140 may also be set for the torque application member 1100 via the controller 1300. The turning angle 1140 enables a user to vary the arc angle through which the torque application member 1100 is turned by a user to reach the particular torque resistance setting at which the torque resistance has been set by a user.

As defined herein, a user may be a therapist who is setting the parameters for a patient to achieve as targeted therapeutic goals or a user may be the patient who is actually utilizing the resistive therapeutic wrist or shoulder dynamometer and exerciser device 1000. In addition, a user may be any other person manipulating the device 1000 such as a manufacturer or repair technician, etc.

As defined herein, an encoder, which functions as a rotary encoder, also called a shaft encoder, is an electro-mechanical device that converts the angular position or motion of a shaft or axle to an analog or digital code. There are two main types: absolute and incremental (relative).

Encoder 1400 measures the angular position of the shaft of the electromagnetic resistance generating member 1200 as applied by the torque application member 1100 and communicates the angular position data with the controller 1300. As disclosed herein, the encoder 1400 may be either an absolute type or an incremental type depending on suitability for the interface with, and characteristics of, the electromagnetic resistance generating member 1200.

In step 100, user U grasps the torque application member 1100 to apply torque to electromagnetic resistance generating member 1200 which is electromagnetic particle brake 1210.

In step 110, the motor encoder 1410 senses the movement of the torque application member 1100 such that in step 120 the controller 1300 emits a signal to the electromagnetic resistance generating member 1200 which is electromagnetic particle brake 1210 and applies a current setting to the electromagnetic particle brake 1210 that represents a target torque value setting.

In step 130, the electromagnetic particle brake 1210 provides resistance to rotation by the user U of the torque application member 1100 based on the current setting applied.

In step 140, the resistance value is displayed on the wireless mobile controller and user interface 1600.

FIG. 6 illustrates a wireless display panel 1700 that wirelessly communicates with the controller and user interface 1600 for the resistive therapeutic wrist dynamometer and exerciser device 1020 according to embodiments of the present disclosure. The large display wireless display panel 1700 may be a touchscreen display that coordinates with the mobile controller and user interface 1600 to control and receive information from the device 1020 by communication means such as Bluetooth or other suitable wireless communications platforms.

Although the generic resistive therapeutic wrist dynamometer and exerciser device 1000 and the specific resistive therapeutic wrist dynamometer and exerciser devices 1010 and 1020 may be operated as independent devices via the mobile controller and user interface 1600, in conjunction with the large display wireless display panel 1700, the following information may be stored and actions may be performed via interaction between the mobile controller and user interface 1600 and the large display wireless display panel 1700:

Display normal charts that show what people of the patient's age and gender should be able to perform

Further details regarding the operational steps enabled by the mobile controller and user interface 1600 are described below with respect to FIGS. 18-24.

FIG. 7A is a cross-sectional view of a commercially available electromagnetic particle brake 1210′ that may be applied as the electromagnetic resistance generating member 1200 represented by generic electromagnetic particle brake 1210 for the resistive therapeutic wrist dynamometer and exerciser devices 1010 and 1020 according to embodiments of the present disclosure. Electromagnetic particle brake 1210′ includes a shaft 1212 rotatably supported by bearings 1214. Magnetic particles 1216 are contained within a gap 1216′ and the gap 1216′ is sealed by magnetic seals 1218. Upon application of a direct current (DC) to a magnetic flux coil 1220, magnetic flux lines 1222 are generated which cause the magnetic particles 1216 to form chains along the flux lines and a torque resistance proportional to the magnetic field strength and correspondingly to the applied DC current is created.

FIG. 7B is a cross-sectional view of the electromagnetic particle brake 1210′ of FIG. 7A that has been further modified to include material shaft seals 1224, e.g., felt, in addition to the magnetic seals 1218 according to embodiments of the present disclosure. Such material shaft seals 1224 were in commercial usage in the past. For the present application to the electromagnetic particle brake for the therapeutic devices 1000, 1010 and 1020, the material shaft seals 1224 advantageously enable the electromagnetic particle brake 1210′ to achieve a zero current, zero resting resistance, thereby overcoming the residual resistance that is found at zero current in currently utilized electromagnetic particle brakes.

FIG. 8A is a graphical plot of torque (in lb.-in.) versus percent of rated input current (%) of an increasing current curve 210 and a decreasing current curve 220 for the electromagnetic particle brake 1210 applied as the electromagnetic resistance generating member 1200 according to embodiments of the present disclosure. The electronic particle brake 1210 creates angular resistance in proportion to the magnitude of the input current, i.e., percent of rated input current.

The curves of percent of rated input current versus torque for increasing current 210 (in the direction of arrow A) and percent of rated input current versus torque for decreasing current 220 (n the direction of arrow B) are stored in memory 1310 in the controller 1300. The current versus torque response of the electromagnetic particle brake 1210 for the two cases of increasing versus decreasing are assumed to remain the same during operation of the devices 1010 and 1020. This is due to the fact that the hysteresis response will not significantly change regardless of the overall number of cycles of operation during usage of the devices 1010 and 1020 by different users.

FIG. 8B is a graphical plot of the torque versus percent of rated input current of FIG. 8A illustrating an area C encircled to show the unpredictability of the path between the increasing current curve 210 and the decreasing current curve 220. To illustrate this, if the torque resistance of the electromagnetic particle brake 1210 for device 1010 or 1020 is initially set at a value of 30% of maximum current value at point A1 on the increasing current curve A, the corresponding torque value is about 23 lb-in.

If the user U then decides to reduce the torque resistance setting by reducing the input current to the electromagnetic particle brake 1210, the torque resistance setting would actually increase to 30 lb-in. as represented by point B1 on the decreasing current curve B. This is contrary to the intended result which is to temporarily remain at 23 lb-in. as represented by point B2 on the decreasing current curve B. This problem would occur if the user U were lowering the torque resistance setting by turning a knob, or tapping a down arrow, or moving a slider control, or by other similar action.

If we were to achieve the intended torque resistance setting of 23-lb-in at point B1 on the decreasing current curve B, the user U should apply about 24% max. current to achieve this.

Referring also to FIG. 8C, which is an enlarged view of the encircled area C of FIG. 8B, when the current is changed from 30% at point B1 to 24% at point B2, the path shown between point A1 on the increasing current curve 210 and the intended point B2 on the decreasing current curve 220 is not predictable. Therefore, whenever the user U wishes to change direction in torque resistance (from increasing to decreasing OR from decreasing to increasing), it is necessary to ensure that the electromagnetic particle brake 1210 will be following a predictable curve.

To address this problem, the controller 1300 is programmed to generate a first pulse from the point A1 on the increasing current curve 210 at 23 lb-in. torque to 100% of maximum current setting. The controller 1300 then decreases as a second pulse the current at 23 lb-in. to 24% of maximum current value at point B2 on the decreasing current curve 220. This assures that the adjustment of the torque resistance setting of the electromagnetic particle brake 1210 is occurring on the proper curve. A specific example of the foregoing pulsing is described below with respect to FIGS. 10A, 11A and 11B.

As will be shown in the examples below in FIGS. 10A-13B, there are cases where the current may be pulsed instead to 0% of maximum rated value.

FIG. 9 is a system logic diagram illustrating the relationship of the controller 1300 to the increasing current curve 210 and the decreasing current curve 220 of FIGS. 8A-8C. More particularly, the increasing current curve 210 and the decreasing current curve 220 are stored in memory 1310 and retrievable either individually or together via AND/OR gate 20 for utilization by the controller 1300 to establish the necessary input current IC to the electromagnetic resistance generating member 1200, which corresponds to electromagnetic particle brake 1210.

In conjunction with FIG. 5, FIG. 10A is a system logic diagram for the controller 1300 recognizing direction of torque change being directed by the user U and proceeding to control the torque according to at least four examples, i.e., Examples 1 to 4. More particularly, as torque is applied in step 100 of FIG. 5, in step 110, the motor encoder 1410 senses movement and in FIG. 10A, in action step 115 of FIG. 10B, the controller 1300 recognizes the direction of torque change as an increase or a decrease of existing torque and retrieves the necessary curve 210 and/or 220 when required. In FIG. 5, in step 120, the controller 1300 emits a signal to the electromagnetic resistance generating member 1200 which is electromagnetic particle brake 1210 and applies a current setting to the electromagnetic particle brake 1210 that represents a target torque value setting. The remaining steps 130 and 140 are then implemented as shown in FIG. 5.

Thus, in FIG. 10B, step 115 is implemented via OR gate 30 wherein the controller 1300, upon recognizing the direction of torque change and on which of the curves 210 or 220 the input current is being controlled selects either of the curves as required to continue operation of the device 1200 according to Examples 1 to 4, numbered as 2100 to 2400, respectively. Examples 2 to 4, 2200 to 2400, are continued on FIGS. 11A-11B, 12A-12B and 13A-13B, respectively.

Example 1, step 2100, is described in 2110 as the input current IC is to increase along the increasing current curve 210 to the target value wherein no pulsing is required.

FIG. 10B is a graphical plot of Example 1 2100 in FIG. 10A wherein the controller 1300 increases input current IC along the increasing current curve 210 via arrow A from an initial current input value of 0% at CI211, corresponding to a torque resistance setting T211 of about 1.0 lb-in. to a target current input value CI212 of 43% of maximum input value, which corresponds to a torque resistance setting T212 of 40 lb-in. Since the increase in input current IC is initiated from the increasing current curve 210, the increase in input current IC continues along the increasing current curve 210 in the direction of arrow A with no pulsing required.

While not illustrated, those skilled in the art will recognize that, while not generally frequently occurring, an analogous example could be illustrated and described to show the case where the input current IC is initially on the decreasing current curve 220 and it is desired to continue decreasing the input current IC along the decreasing current curve 220.

FIG. 11A is a system logic diagram for the controller 1300 to decrease input current IC when initially on the increasing current curve 210 as Example 2, 2200, of FIG. 10A. Example 2 is described in 2210 as the input current IC is to decrease from the increasing current curve 210.

FIG. 11B is a graphical plot of Example 2, 2200, in FIG. 11A wherein the controller 1300 decreases input current IC when initially on the increasing current curve 210.

Referring to FIG. 11A in conjunction with FIG. 11B, in step 2220, the input current IC is pulsed via pulse P2201 to 100% of maximum value from the existing current value CI221 of about 42% of maximum current value on the increasing current curve 210, corresponding to an initial torque resistance setting T221 of 40 lb-in.

In step 2230, the pulse P2201 is returned via pulse P2202 to the same value of torque resistance setting T221 on the decreasing current curve 220 of 40 lb-in. at about 37% of maximum current value CI222 as the torque value initially on the increasing current curve 210.

In step 2240, the adjustment of the input current IC is continued by decreasing the input current IC to the target torque value T222 of about 25 lb-in., corresponding to a 25% maximum current value CI 223.

FIG. 12A is a system logic diagram for the controller 1300 to increase input current IC when initially on the decreasing current curve 220 as Example 3, 2300, of FIG. 10A. Example 3 is described in 2310 as the input current IC is to increase from the decreasing current curve 220.

FIG. 12B is a graphical plot of Example 3, 2300, in FIG. 12A wherein the controller 1300 increases input current IC when initially on the decreasing current curve 220.

Referring to FIG. 12A in conjunction with FIG. 12B, in step 2320, the input current IC is pulsed via pulse P2301 to 0% of maximum value from the existing current value CI231 of about 25% of maximum current value on the decreasing current curve 220, corresponding to an initial torque resistance setting T231 of 25 lb-in.

In step 2330, the pulse P2301 is returned via pulse P2302 to the same value of torque resistance setting T231 on the increasing current curve 210 of 25 lb-in. at about 30% of maximum current value CI232 as the torque value initially on the decreasing current curve 220.

In step 2340, the adjustment of the input current IC is continued by increasing the input current IC to the target torque value T232 of about 70 lb-in., corresponding to a 63% maximum current value CI233.

FIG. 13A is a system logic diagram for the controller 1300 to decrease input current IC when initially on the increasing current curve 210 while circumventing adjustment on either the increasing current curve 210 or on the decreasing current curve as Example 4, 2400, of FIG. 10A. Example 4 is described in 2410 as the input current IC is to decrease from the increasing current curve 210.

FIG. 13B is a graphical plot of Example 4, 2400, in FIG. 13A wherein the controller 1300 decreases input current IC when initially on the increasing current curve 210.

Referring to FIG. 13A in conjunction with FIG. 13B, in step 2420, the input current IC is pulsed via pulse P2401 to 100% of maximum value from the existing current value CI241 of about 63% of maximum current value on the increasing current curve 210, corresponding to an initial torque resistance setting T241 of 70 lb-in.

Step 2430 includes circumventing adjustment of the input current IC on either the increasing current curve 210 or on the decreasing current curve 220 by instead immediately setting the input current IC at the value on the decreasing current curve 220 corresponding to the target decreased torque value T242 of 20 lb-in., thereby pulsing across the increasing current curve 210 via pulse P2402 to an input current value CI242 of about 23% of maximum current value on the decreasing current curve 220.

FIG. 14 is an elevation view of the contents of internal compartment 1024 of the rectangular or box-like shaped enclosure 1022 of the resistive therapeutic wrist dynamometer and exerciser device 1020 (and may similarly be applied to the internal contents of the clock-like enclosure 1012 of the resistive therapeutic wrist dynamometer and exerciser device 1010). More particularly, torque application member 1100 includes a torque application attachment, e.g., torque application members 1100 a-1100 i as described above with respect to FIGS. 2A-2E, and electromagnetic particle brake 1210 (see FIGS. 7A-7B) wherein the torque application member 1100 is commonly mounted on centerline shaft 1212 of the cylindrically shaped electromagnetic particle brake 1210 on a user side 1000′ of the devices 1010 and 1020. Centerline shaft 1212 extends through the electromagnetic particle brake 1210 to a computational side 1000″ of the devices 1010 and 1020. An encoder wheel 1420 is mounted on the computational side 1000″ of the centerline shaft 1212 and engages encoder shaft 1415 of encoder 1410 at contact line 1415′ with the encoder wheel 1420. The contact between the encoder wheel 1420 and the encoder shaft 1415 enables monitoring of angular rotation of the encoder wheel 1420 caused by rotation of the centerline shaft 1212 as a user applies torque to the torque application member 1100. Dimension A=shows the distance between the user side 1000′ and the computational side 1000″. An antenna 1350 enables wireless communication between the controller 1300 and controller and user interface 1600 and large display wireless display panel 1700 of FIGS. 4-6.

FIG. 15 is s rear view or computational side 1000″ of the resistive therapeutic wrist dynamometer and exerciser device 1020 of FIGS. 4-6, 7A-7B and 14 illustrating the encoder wheel 1420, encoder 1410 and encoder shaft 1415 and centerline shaft 1212 of the electromagnetic particle brake 1210 which operate to monitor angular rotation of the encoder wheel 1420 caused by rotation of the centerline shaft 1212 as a user applies torque to the torque application member 1100, as described above with respect to FIG. 14.

FIG. 16 is another elevation view of the contents of internal compartment 1024 as described above in FIGS. 14 and 15 and further including the rectangular or box-like shaped enclosure 1022 of the resistive therapeutic wrist dynamometer and exerciser device 1020 (and may similarly be applied to the internal contents of the clock-like enclosure 1012 of the resistive therapeutic wrist dynamometer and exerciser device 1010). Since the contents of internal compartment 1024 have been described above with respect to FIGS. 14 and 15, only those additional features not appearing in those figures will be described herein.

More particularly, the torque application member 1100 is positioned on centerline shaft 1212 and externally of the enclosure 1012 or 1022 on user side 1000′ to enable a user to apply torque to the torque application member 1100. Also shown positioned externally of the enclosure 1012 or 1022 are the circular arc of light-emitting diode (LED) lights 1150 that enable measurement of the turning angle 1140 and which are positioned circumferentially around the centerline shaft 1212 that extends externally of the enclosure 1012 or 1022 and the electromagnetic particle brake 1210 that is generally positioned internally of the enclosure 1012 or 1022. Also positioned externally of the enclosure 1012 or 1022 is the controller and user interface 1600 that is by way of example shown mounted above the circular arc of LEDs 1150.

Not shown in FIG. 14 but also mounted internally of the enclosure 1012 or 1022 is the controller 1300 and memory 1310 that communicate wirelessly via the antenna 1350 with the controller and user interface 1600 and where applicable with the wireless display panel 1700. Also included within the enclosure 1012 or 1022 is a power supply 1800 that is in communication with the controller 1300, the electromagnetic particle brake 1210, the controller and user interface 1600 and all other components requiring supply of electrical power.

Although not separately illustrated, audio feedback capability from the controller and user interface 1600 and where applicable with the wireless display panel 1700 are possible.

FIG. 17 illustrates a master display screen 1605 of the controller and user interface 1600 for the resistive therapeutic wrist dynamometer and exerciser device 1000 (or 1010 or 1020) according to embodiments of the present disclosure. The master display screen 1605 includes a link 1610′ to an “Evaluate” display, a link 1630′ to a “Resistive” display, and a link 1650′ to a “90°” or “Angle” display. Upon a user accessing, pressing or touching any of the links, the controller and user interface 1600 transfers to the appropriate display as shown in FIGS. 18-20 following.

FIG. 18 is the “Evaluate” display screen 1610 with label 1611 “Evaluate” that appears when a user touches the “Evaluate” link 1610′ in the master display screen 1605 in FIG. 17. In this mode, the controller 1300 emits a signal to the electromagnetic resistance generating member 1200, e.g., the electromagnetic particle brake 1210, to apply maximum current from the power supply 1800 to effectively lock the electromagnetic particle brake 1210 to so that upon a user applying torque to the torque application member 1100, visible rotation or movement of the torque application member 1100 is for practical purposes prevented. This condition allows recordation by the controller 1300 of the maximum torque the user can apply to the torque application member 1100.

More particularly, the encoder 1410 transmits movement indication to the controller 1300 and the controller 1300 increases input current IC until the user cannot move the torque application member 1100 any further, meaning there is no movement detected from the encoder 1410. Thus, the maximum torque that the particular user can attain in either the clockwise or the counterclockwise direction is known.

In a box 1612, instructions are provided for the user to “Start by tapping Clockwise Play button and have User turn device SLOWLY as hard as possible. Tap DONE button when complete. Repeat same for Counter-Clockwise. Automatically set RESISTIVE mode to desired percentage by tapping bottom button.” The “Evaluate” display 1610 includes a “Home” touch key 1614 and a “Reset” touch key 1616. Additionally, “Clockwise Play” button 1618 a 1 enables the user to start the measurement of clockwise torque applied to the torque application member 1100 wherein the numerical value is shown on clockwise display 1618 a 2 in the example as “658.9”. The user can tap the Clockwise “Done” button 1681 a 3 when the clockwise turning is complete.

The “Counterclockwise Play” button 1618 b 1 enables the user to continue by then starting measurement of counterclockwise torque applied to the torque application member 1100 wherein the numerical value is shown on counter clockwise display 1618 b 2 in the example as “658.9”. The units for the displays 1618 a 2 and 1618 b 2 may be set in “lb-in” via touch button 16181 or in “N-m” via touch button 16182. The units in which the device 1000 is reading is indicated by whether the display 1618 a 2 or display 1618 b 2 is lit.

Advantageously, it is very desirable for the user to automatically set the value on the “Set Resistive to XX %” display button 1620 wherein 30% is shown as an example setting. The Resistive setting may be increased by the user touching the increase arrow 1621 and may be decreased by the user touching the decrease arrow 1622.

As explained in more detail for FIG. 19, in the RESISTIVE mode, the user exercises to a percentage of the maximum value attained in each direction, i.e., clockwise or counterclockwise. The therapist/user can immediately move to the RESISTIVE mode by tapping the “Set Resistive to XX %” display button 1620.

Upon completion of the EVALUATE mode in display 1610, the Reset button 1616 may be tapped to set the readings in displays 1618 a 2 and 1618 b 2 and the “Set Resistive to XX %” display and button 1620 each to zero if the therapist or user wishes to repeat the testing. Tapping the Reset button 1616 always returns the settings to zero. It is very desirable to automatically set the RESISTIVE mode where the user will exercise to a percentage of the maximum value attained in each direction. The therapist/user can immediately move to the RESISTIVE mode by tapping the “Set Resistive to XX %” display and button 1620 wherein for example the RESISTIVE will be preset at 30% of the measured values as a default value. The therapist/user can change that percentage value before tapping that button 1620 by tapping the up and down arrows 1621 and 1622, respectively. With consideration of the fact that the User has likely been injured, if the Therapist considers 30% to be inadequate or too strenuous, the Therapist can change the setting via the “Set Resistive to XX %” display and button 1620.

FIG. 19 is the “Resistive” display screen 1630 with label 1631 “Resistive” that appears when a user touches the “Resistive” link 1630′ in the master display screen 1605 in FIG. 17. In the “Resistive” mode, the device 1000 is set so that a user exercises at set torque tensions or settings that remain constant during application of torque by the user to the torque application member 1100. In the “Resistive” mode, the controller 1300 unlocks the electromagnetic particle brake 1210 to enable visible movement of the torque application member 1100.

In a box 1632, instructions are provided for the user to “Using the slider and buttons, adjust the Resistance for Clockwise and Counter-Clockwise. Tap Green PLAY Button to START”.

The “Resistive” display 1630 also includes a “Home” touch key 1634 and a “Reset” touch key 1636. The display 1630 includes a “Clockwise Resistance” setting slider 1638 a wherein the setting may be increased by moving the setting slider 1638 a in the direction of arrow 1638 a 1 and may be decreased by moving the setting slider in the direction of arrow 1638 a 2.

A clockwise arrow CW is positioned adjacent to clockwise torque resistance setting display 1640 a to indicate to the user the direction of the torque resistance display value visible on display 1640 a.

Similarly, the display 1630 includes a “Counterclockwise Resistance” setting slider 1638 b wherein the setting may be increased by moving the setting slider 1638 b in the direction of arrow 1638 b 1 and may be decreased by moving the setting slider in the direction of arrow 1638 b 2.

A counterclockwise arrow CCW is positioned adjacent to counterclockwise torque resistance setting display 1640 b to indicate to the user the direction of the torque resistance display value visible on display 1640 b.

Starting measurement of either clockwise torque or counterclockwise torque applied to the torque application member 1100 occurs by the user touching or pressing the “Start” or “Play” button 1642 wherein the numerical value of the torque is shown on clockwise display 1640 a and on counterclockwise display 1640 b each in the example as “658.9”. Again, the units for the displays 1640 a and 1640 b may be set in “lb-in” via touch button 16401 or in “N-m” via touch button 16402.

After starting, the torque resistance setting is shown on display 16441 adjacent to the “Start” or “Play” button 1642 as well as a timer 16442 while the number of repetitions is shown in “Reps” display 16443. The numerical settings for clockwise CW and counterclockwise CCW torque resistance are set up using the controls 1638 a 2, 1638 a, 1638 a 1, 1638 b, 1638 b 1, and 1638 b 2. As the controls are used, the results are displayed on CW and CCW displays 1640 a and 1640 b, respectively. 16441 is the timer. When the user taps Start, 1642, the timer 16441 starts at 00:00 and starts showing how much time has elapsed in seconds.

The display 1630 further includes an “Angle” display 1646 with a “Peak Clockwise Angle” or “Peak” display 1646 a 1 and an “Average Peak Clockwise Angle” or “Avg Peak” display 1646 a 2 on the lower right side of display 1630 and a “Peak Counterclockwise Angle” or “−Peak” display 1646 b 1 and an “Average Peak Counterclockwise Angle” or “−Avg Peak” display 1646 b 2 on the lower left side of display 1630.

Referring to the circular LED lighting display 1150 in FIG. 4-6 and the torque application members 1100 a-1100 f shown in FIGS. 2A-2E, depending on the type of torque application member 1100 being utilized for the exercising, the 0 degree reference for the “Angle” display 1646 may be set at any clock position ranging generally from 12 o'clock to 3 o'clock, to 6 o'clock, to 9 o'clock, back to 12 o'clock, etc. The angle reading indicated in “Angle” display 1646 will be represented by correspondingly lighting up each LED in the circular arc 1150 and on the “Angle” display 1646.

For example, if utilizing the door handle 1100 a in FIG. 2A, it would be most appropriate for the therapist to set the “Angle” to zero at the 3 o'clock position since the door handle 1100 a is oriented in the rest or untorqued position at the 3 o'clock position. If utilizing the key 1100 e in FIG. 2C, the 0 degree reference for the “Angle” display 1646 would be most appropriately set by the therapist at the 12 o'clock position since the key 1100 e in the untorqued position would span the 12 o'clock to 6 o'clock positions and the user will turn the key either CW or CCW from the 12 o'clock position. In the case of the door knob 1100 f, which is circular, the therapist could set the 0 degree reference for the “Angle” display 1646 at virtually any position ranging from 12 o'clock all the way around by 360 degrees.

If the user enters the “Resistive” display 1630 from the “Evaluate” display 1610, the numerical settings for clockwise CW and counterclockwise CCW torque resistance are set up in displays 1640 a and 1640 b will have been preset.

If not, and at any time, the therapist/user can change the numerical settings for clockwise CW and counterclockwise CCW torque resistance by adjusting the slider 1638 a and buttons 1638 a 1 and 1638 a 2 to the immediate left and right of the slider 1638 a for CW torque resistance. The left/right buttons 1638 a 1 and 1638 a 2 enable adjustment of the torque resistance in increments of 0.1 lb-in or 0.1 N-m. If desired, other increment values can be established.

The therapist/user taps the “Start” or “Play” button 1642 to begin. This sets the angle in display 1646 to 0, the time in display 16441 to 0:00, and the Reps count in display 16443 to 0.

The time display 16441 will show how long the user has been exercising.

The number of repetitions in the “Reps” display 16443 will increase by one increment every time the torque application member 1100 crosses 0 degrees or 360 degrees.

The “Angle” display 1646 will show the current angle and go to 360 degrees and then start over again from the 0 degree reference while going clockwise CW. If going counterclockwise CCW, the “Angle” display 1646 will show negative values. So, if the user goes 190 degrees clockwise, and then reverses direction, the “Angle” display 1646 will count backwards until it hits 0: 189, 188, 187, etc. If the user continues counterclockwise CCW after 0, the reading in “Angle” display 1646 will be negative.

The PEAK (Max) Angle displays 1646 a 1 and 1646 b 1 and Average PEAK Angle displays 1646 a 2 and 1646 b 2 illustrate those values for both the clockwise CW and the counterclockwise CCW directions, respectively. A good example is a shoulder exercise where the user is repetitively moving his or her shoulder clockwise and counterclockwise. The therapist may want to know the range of motion via the Peak displays 1646 a 1 and 1646 b 1 and the “Average Peak” displays 1646 a 2 and 1646 b 2.

The “Reset” button 1636 sets the “Reps” display 16443, the “Angle” displays 1646, 1646 a 1, 1646 a 2, 1646 b 1 and 1646 b 2 and the “Time” display 16441 back to zero. However, the Resistance values in displays 1640 a and 1640 b will remain where last set.

FIG. 20 illustrates the “Angle” display screen 1650 with label 1651 “Angle” shown by example as “Angle=90°” that appears when a user touches the “Angle” or “90°” link 1650′ in the master display screen 1605 in FIG. 17. As in the case of the “Resistive” display 1630, in the “Angle” or “90°” mode, the controller 1300 unlocks the electromagnetic particle brake 1210 to enable visible movement of the torque application member 1100 if transferring from the “Evaluate” mode 1610 where the electromagnetic particle brake 1210 was locked.

In the “Angle” mode, the torque resistance setting is increased to cause the user to exercise with increasing difficulty as the user turns the torque application member 1100.

The “Angle” display screen 1650 again includes a “Home” button 1654 to return to the master display screen 1605 shown in FIG. 17 and a “Reset” button 1656 to reset the values shown on display screen 1650.

In a box 1652, instructions are provided for the user to “Tap Button for Clockwise or Counter-Clockwise. Then, using the slider and buttons, adjust the Resistance for + or −90 Degrees. Tap Green PLAY Button to START”.

Thus, when selecting the link 1650′ to “90°” or “Angle” display “90°” from master display screen 1605 shown in FIG. 17, in the “Angle” or “90°” display screen 1650, the user must select the direction of rotation of the torque application member 1100 is to be attempted, i.e., clockwise or counterclockwise by pressing the CW circle or the CCW circle on toggle button 1658.

By moving slider 1660 in the direction of arrow 1661 or in the direction of arrow 1662, the user may increase or decrease, respectively, the torque resistance setting shown in display 1664. In a similar manner as before, the units for the torque resistance setting display 1664 may be set in “lb-in” via touch button 16641 or in “N-m” via touch button 16642.

In a similar manner as display 1630 in FIG. 19, the display 1650 further includes an “Angle” display 1666 with a “Peak Clockwise Angle” or “Peak” display 1666 a 1 and an “Average Peak Clockwise Angle” or “Avg Peak” display 1666 a 2 on the lower right side of display 1630 and a “Peak Counterclockwise Angle” or “−Peak” display 1666 b 1 and an “Average Peak Counterclockwise Angle” or “−Avg Peak” display 1666 b 2 on the lower left side of display 1650.

The display 1650 further includes a “Torque” display 1668 that represents current input and a “Peak” torque display 16681 and an “Avg Peak” or average peak torque display 16682 both of whose readings are based on the readings of the “Torque” display 1668.

As indicated in the instruction box 1652, the user presses “PLAY” or “START” button 1670, torque value appears on display 1671 and the time since starting on timer 1672. The number of repetitions is displayed on “Reps” display 1673.

Referring again to the circular LED lighting display 1150 in FIG. 4-6 and the torque application members 1100 a-1100 f shown in FIGS. 2A-2E, depending on the type of torque application member 1100 being utilized for the exercising, the 0 degree reference for the “Angle” display 1666 may be set at any clock position ranging generally from 12 o'clock to 3 o'clock, to 6 o'clock, to 9 o'clock, back to 12 o'clock, etc. The angle reading indicated in “Angle” display 1666 will be represented by correspondingly lighting up each LED in the circular arc 1150 and on the “Angle” display 1666.

As a specific example, assuming the therapist/user selects the clockwise CW direction via toggle button 1658, the therapist/user changes, via the slider 1661, the maximum torque resistance value desired upon the user achieving 90 degrees by moving slider 1660 in the direction of arrow 1661 or in the direction of arrow 1662.

The objective is that the further the user turns the torque application member 1100, the torque resistance setting increases to make further turning more difficult. The User may NOT be able to turn the torque application member 1100 the full 90 degrees and many different results may wind up being displayed. The therapist may ask the patient to do 10 repetitions and may wish to know what is the highest resistance attained and the average high resistance for the whole set.

Assume an example where torque application member 1100 is door handle 1100 a and it desired that the user try to turn the door handle 1100 a clockwise 90 degrees and at that point achieve a 9-lb-in resistance. The Therapist would first click the toggle button 1658 to select the clockwise CW direction. Then, moving slider 1660 in the direction of arrow 1661 or in the direction of arrow 1662, the Therapist can set the 90 degree resistance to 9.00-lb-in as displayed on torque resistance setting display 1664. The Therapist presses “PLAY” or “START” button 1670 and the User starts turning the door handle 1100 a. As the User turns door handle 1100 a for example by 10 degrees, “10.0” will be displayed at “Angle” display 1666. Since this is the first iteration, CW “Peak” display 1666 a 1 and CW “Avg. Peak” display 1666 a 2 will also indicate 10 degrees. CCW “−Peak” display 1666 b 1 and CCW “−Avg. Peak” display 1666 b 2 will read zero since the User is turning the door handle 1100 a clockwise CW. The Torque resistance is now 1.0-lb-in and that is indicated in “Torque” display 1668. Since this is the first iteration, “Peak” torque display 16681 and “Avg. Peak” torque display 16682 will also indicate 1.0-ln-in.

The User continues to turn the door handle 1100 a and has now reached 20 degrees so 20.0 will be displayed at “Angle” display 1666. Since this is still the first iteration, CW “Peak” display 1666 a 1 and CW “Avg. Peak” display 1666 a 2 will also indicate 20 degrees. Again, CCW “−Peak” display 1666 b 1 and CCW “−Avg. Peak” display 1666 b 2 will read zero since the User is turning the door handle 1100 a clockwise CW. The Torque resistance is now 2.0-lb-in and that is indicated in “Torque” display 1668. Since this is still the first iteration, “Peak” torque display 16681 and “Avg. Peak” torque display 16682 will also indicate 2.0-lb-in.

The user can go past 90 degrees and the resistance will continue to increase. In the above example, the torque resistance will therefore go to 10.0 lb-in at 100 degrees.

Now assume that is as much as the User can turn the door handle 1100 a. The User than starts turning the door knob counterclockwise CCW to return the door handle 1100 a to the 0 Degree reference position. As the User turns the door handle 1100 a counterclockwise CCW, there is no resistance. So 0.0 is displayed on “Torque” display 1668. The immediate Angle is displayed on “Angle” display 1666 as the User turns counterclockwise CCW (20, 19, 18, . . . 0.0). CW “Peak” display 1666 a 1 and CW “Avg. Peak” display 1666 a 2 continue to indicate 20.0. “Peak” torque display 16681 and “Avg. Peak” torque display 16682 continue to indicate 2.0-lb-in. When the User reaches 0.0 Degrees, the “Reps” display 1673 now indicates 1 repetition.

Now the User starts turning clockwise CW again for a second iteration. Assuming the User has turned the door handle 1100 a 10 degrees, 10.0 will be displayed at “Angle” display 1666. CW “Peak” display 1666 a 1 still indicates 20.0 degrees since that Peak angle has not been exceeded. Since this is the second iteration, CW “Avg. Peak” display 1666 a 2 will indicate 15 degrees, i.e., this results from the average of the CW Peak angle 1666 a 1 reading of 20.0 degrees and the current “Angle” display 1666 reading of 10.0 degrees. The torque resistance is now 1.0-lb-in and that is indicated in “Torque” display 1668. “Peak” torque display 16681 will continue to indicate 2.0-lb-in since that is still the Peak and “Avg. Peak” torque display 16682 will indicate 1.5-lb-in, i.e., this results from the average of the “Peak” torque display 16681 reading of 2.0 lb-in. and the current torque resistance indicated in “Torque” display 1668 of 1.0 lb-in.

Now assume the User is able to achieve 30 Degrees rotation of the door handle 1100 a before stopping and turning the door handle 1100 a counterclockwise CCW to 0.0 Degrees. At 30 Degrees, “Angle” display 1666 will indicate 30.0 degrees. CW “Peak” display 1666 a 1 now indicates 30.0 degrees since that is the new Peak Angle. CW “Avg. Peak” display 1666 a 2 now indicates 25.0 degrees, i.e., this results from the average of the previous Peak Angle at 20.0 degrees and the new Peak Angle of 30.0 degrees. “Torque” display 1668 indicates 3.0-lb-in. “Peak” torque display 16681 now indicates 3.0 since that is the new Peak Torque Resistance. “Avg. Peak” torque display 16682 now indicates 2.5-lb-in, i.e., this results from the average of the previous Peak Torque (2.0 lb-in.) and the new Peak Torque (3.0-lb-in).

The sequence of events may continue in the same manner to increase the number of repetitions indicated on the “Reps” display 1673 or in any of numerous and variable scenarios available to the Therapist and User via the various torque application members 1100 a-1100 f available and the possible therapeutic operating scenarios available due to the functionality of the device 1000.

More particularly, in step 302, the user turns the torque application member 1100 clockwise CW or counterclockwise CCW.

In step 304, the therapist/user adjusts resistance level during turning of the torque application member 1100.

Following step 306, via OR gate 40 the generic resistive therapeutic wrist dynamometer and exerciser device 1000 and as executed by the specific devices 1010 and 1020 and the controller and user interface 1600 in step 308 may cause the torque application member 1100 to remain in position or in step 312 may cause the torque application member 1100 to return to START, e.g., by resetting the reset buttons 1616, 1636 or 1656, etc.

If step 308 occurs, in step 310, the user turns the torque application member 1100 clockwise CW or counterclockwise CCW while maintaining the same torque setting resistance level.

If step 312 occurs, referring now to continuation A′ on FIG. 22, via OR gate 50, in step 314, the therapist/user sets a constant torque resistance setting, e.g., maximum resistance position 1130 (see FIG. 1A).

In step 316, the generic resistive therapeutic wrist dynamometer and exerciser device 1000 and as executed by the specific devices 1010 and 1020 detects the maximum resistance the user can reach.

Continuing on FIG. 22, in step 320, the therapist/user sets the torque resistance to increase as the user turns the torque application member 1100 further away from the neutral resistance position 1110 (see FIG. 1A).

In step 322, the therapist sets the maximum resistance position 1130 at the specified turning angle 1140, e.g., at 90° (see FIG. 1A).

In step 324, the generic resistive therapeutic wrist dynamometer and exerciser device 1000 and as executed by the specific devices 1010 and 1020 detects the maximum resistance the user can reach.

In step 326, the generic resistive therapeutic wrist dynamometer and exerciser device 1000 and as executed by the specific devices 1010 and 1020 provides, via the controller 1300 and control and user interface 1600, a signal if the user reaches the set constant torque resistance, as shown via continuation B′ on FIG. 23.

Referring now to FIG. 23, following steps 318 or 326, via AND/OR gate 60, the generic resistive therapeutic wrist dynamometer and exerciser device 1000 and as executed by the specific devices 1010 and 1020 provides, via the controller 1300, provide in step 328 visual feedback such as in the form of the LED lights 1150 indicating the distance that the torque application member 1100 was turned.

In step 330, the visual feedback signal is sent to the mobile device, e.g., the control and user interface 1600.

Alternatively, or in addition, the generic resistive therapeutic wrist dynamometer and exerciser device 1000 and as executed by the specific devices 1010 and 1020 provides, via the controller 1300, provide in step 332, audio feedback such as in the form of a musical tone or a beep or siren, etc.

In step 334, the audio signal is sent to the mobile device, e.g., the control and user interface 1600.

Turning now to FIG. 24, there is illustrated an exploded view of an alternate embodiment of a resistive therapeutic wrist dynamometer and exerciser device. More particularly, in conjunction with FIGS. 1A-1B and 2A-2E, resistive therapeutic wrist dynamometer and exerciser device 1030 includes torque application member 1100 shown by example in the form of door knob 1100 f that is removably attachable to electromagnetic resistance generating member 1200 that includes a flywheel 1220 and a pair of electromagnetic motors 1222 a and 1222 b that are in contact with the flywheel 1220 to create resistance. The torque application member 1100 in the form of door knob 1100 f attaches to the central shaft 1220′ of the flywheel 1220. The device 1030 further includes a motor 1224 to return the flywheel 1220 to the neutral position.

FIG. 25 illustrates a hardware configuration drawing for the internal compartment 1044 of the enclosure 1042 of another embodiment of a resistive therapeutic wrist dynamometer and exerciser device 1040. In conjunction with FIG. 1B, device 1040 includes a torque converter 1260 in the form of a circular gear for increasing mechanical torque. Torque application member 1100 is removably attached to the central shaft of the circular gear 1260. The torque converter or gear 1260 is connected via a belt 1264 to an electric motor 1262 and one or more encoders 1460.

FIG. 26 is a schematic logic diagram showing operational steps of the resistive therapeutic wrist dynamometer and exerciser device 1040 of FIG. 25.

In step 100′, user U grasps the torque application member 1100 to apply torque to torque converter 1260 via torque application member 1100.

In step 110′, the motor encoder 1460 senses the movement of the torque application member 1100 such that in step 120′ the controller 1300 emits a signal via the antenna 1350 to the electromagnetic resistance generating member 1200 which is electric motor 1262 and applies a current setting to the electric motor 1262.

In step 130′, the motor 1262 provides torque resistance based on the input current to represent a target torque value setting.

In step 140′, the motor 1262 and torque converter 1260 provide resistance to rotation by the user U of the torque application member 1100 based on the current setting applied.

It should be noted also that the steps relating to setting levels and maximum settings in methods in FIGS. 5, 10A, 11A, 12A, 13A, 21, 22, 23 and 36 and with respect to the methods of operating the mobile controller and user interface 1600 in FIGS. 17-20 may generally be performed in any order deemed appropriate for the user or therapist and not necessarily in the sequences illustrated in those figures.
